摘要

当前燃气冷热电联供（combined cooling，heating and power，CCHP）分布式能源系统在国内取得一定的发展，但由于系统规模及配置不合理，导致CCHP系统运行效率低、经济性较差、运行效果不理想，甚至导致部分CCHP系统停运的情况。以四川省某综合性三乙医院为例，通过分析当前医院冷、热、电负荷现状，预测新建医院分院的冷、热、电负荷，针对性地确定其CCHP系统的装机规模和系统配置，以实现CCHP系统经济高效运行。通过与传统分供系统对比，从经济效益、能源利用效率、环境效益3个方面综合分析了医院CCHP系统的合理性。

Abstract

Gas-fired combined cooling

heating and power (CCHP) distributed energy system has made certain progress in China. However

because of unreasonable system design scale and configuration compared with demand

the CCHP system has low operating efficiency

poor economy

unsatisfactory operation effect

and even some of the CCHP systems have been shut down. Taking a middle first-class hospital in Sichuan province as an example

by analyzing current hospital's cooling

heating and power loads on typical day

the cooling

heating and power loads in the newly built hospital branch were projected

and the installed scale and system configuration of CCHP system were specifically determined to realize the economical and efficient operation of CCHP system. Compared with the traditional energy supply system

the rationality of CCHP system in hospital was analyzed from three aspects including economic benefit

energy utilization efficiency and environmental benefit.
